Company email (April 2015):
"Isinglass is commonly used prior to filtering in the brew process and we do use it as well. But unlike other brewers that use isinglass, we completely filter out all the Isinglass rather than simply transfer the beer and let you drink some of it.

We’re very committed to what is going into our beer, and being transparent about it. Here are a few links for you.

Company email (January 2015):
"Hold the press, I just got an update & we have started using isinglass in additional beers. It’s used in Ten Fidy, Gubna, Deviant, and Pinner. Glad I checked in. Looks like some things have changed after all."

Company email (January 2015):
"Thanks for reaching out to us about our big ‘ol craft beer in a can. Ten FIDY is the only brew of ours which is not VEGAN. FIDY uses isinglass containing ground up fish swim bladders as a fining agent. Canned elsewhere, o HELL NO. We’re a hands on group, ain’t nobody else making or packaging our beer. We’re to anal retentive for that type o think, plus we dig making it all happen every day."

Company email (December 2011):
"As explained in our conversations in August Ten FIDY is the only brew of ours which is not Vegan because of the fining agent."

UPDATE
Company email when asked if there were non-vegan products used:
"No sir. "
